# How do you simplify (xy) ^-1?

Jan 17, 2017

See the simplification process below:

#### Explanation:

To simplify this express use these two rules for exponents:

$y - \textcolor{red}{2} = \frac{1}{2} x - 2$

${a}^{\textcolor{red}{1}} = a$

${\left(x y\right)}^{\textcolor{red}{- 1}} \to \frac{1}{x y} ^ \textcolor{red}{- - 1} \to \frac{1}{x y} ^ \textcolor{red}{1} \to \frac{1}{x y}$
